The world's largest maker of construction and mining equipment is reporting earnings of $960 million, or $1.45 per share, compared with $1.7 billion, or $2.54 per share a year ago. Revenue slid 15.8 percent to $14.63 billion.

That's well short of Wall Street's expectations. Analysts surveyed by FactSet had expected a profit of $1.69 per share on revenue of $15.09 billion.

The global mining industry is slowing because of slower growth in China and slower demand for mining gear.
